Not wanting to spam your blog.. but we have recently developed two plug ins for wordpress.
This one displays real time streaming quotes for markets,commodities and forex.. you can choose which markets to display and colors etc

And this one allows you to display our news headlines from one of our sections..

Because of the data charges and bandwidth we do ask for links to stay intact, but they are not too obtrusive!..

Hope this is of interest.
